Abstract

Abstract

Based on the displacement, stress and energy coupled monitoring technique, the trends of subsidence rate, characteristic parameters of acoustic emission, and seepage in the subsidence area were statistically analyzed, respectively. The seepage influence on structural dynamic damage was evaluated synthetically. The result showed that the deformation rate was accelerating seriously and the evaluative trend between seepage and damage can be simply estimated by acoustic emission monitoring.
